GUARD FOR PAPER-WINDING MACHINES.

Application filed February 15, 1927.

This invention relates to guards for paper winders and more particularly to guards for winders known on the market and to the trade as double drum winders.

In double drum paper winding machines as now used, a curved shield extends around a portion of the front winding drum leaving the space between said drum and the roll being wound unprotected, and this constitutes the danger point.

A primary object of the invention is to provide a. simple and efiicient, as well as unique guard for protecting this danger point and which automatically conforms to the size of the roll being wound and when the roll has been wound the guard may be swung to out-of-the-way position and there held during the removal of the finished roll and its replacement by anew shaft and core.

In carrying out these objects, the invention is susceptible of a wide range of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention; there being shown in the drawings for illustrative purposes, a preferred and practical form in which Figure 1 represents a front elevation of the winder guard constituting this invention shown applied with parts broken off for convenience in illustration,

Figure 2 represents a similar view looking in the direction opposite to that shown in Fig. 1,

Figure 3 is an end elevation of a portion of the winder with its winder guard shown in operative position and in various positions,

Fig. 4 is a detail perspective view of one of the fingers employed in the guard,

Fig. 5 is a similar view of the control arm and Fig. 6 is a perspective view detached of the control rest used in the application of the invention.

In the adaptation of the invention as shown, a portion of a double drum winding machine is illustrated at 1 and includes two winding drums 2 and 3 equipped with the usual curved shield 4 which protects the front portion of the drum 3. Shown in dotted lines at 5 between the drums 2 and 3 is a shaft and core such as are used at the begin- Serial No. 168,392.

protected by the improved guard constituting this invention lies between the roll 6 and the drum 3. V

The guard 10 embodying this invention is hingedly mounted on the upper portion at the front of the shield 4 which constitutes a part of the winder machine. 7

This guard 10 comprises a bar 11 of a length conforming to the width of the machine in connection with which it is to be used and which has secured thereto by riveting or otherwise, a plurality of spaced fingers 12, any desired number of which may be employed, 56 being used in the form herein illustrated. One of these fingers 12 is shown in detail in Fig. 4 and may be made of any suitable material preferably of metal, and has its free end rounded as shown at 13 and its inner end which is connected to the bar 11 provided with two fastener receiving openings 14 arranged out of alinement to effect a strong connection of the finger with the bar.

This bar 11 is hingedly connected with the shield 4 by a plurality of spring hinges 15, any desired number of which may be used, and which are spaced suitable distances apart to securely support the guard and permitit to swing toward and away from the roll being wound, said fingers 12 resting on the.

shield 4 at starting, as is shown clearly in Fig. 4 and afterward on the roll 6.

The bar 11 extends at one end beyond the roller 6 being wound, and is equipped with what may be termed a controller arm 16 which extends laterally therefrom in the same direction as the fingers 12 and is designed for manually manipulating the guard.

' Mounted on the frame of the machine is a controller rest in the form of a standard 17 having an attaching foot 18 at its lower end and a laterally opening socket 19 at its upper end above which is arranged a downwardly inclined guard 20 for directing the arm 16 into said seat when it is desired to turn down the guard 10 into inoperative position and hold it so as shown in dotted lines at the right of Fig. 3.

It will thus be seen that this guard 10 which is shown mounted on the shield 4 already in use on winding machines and completely protects the danger point between the drum 3 and the roll 6.

It is obvious that this guard 10 which is simple in construction and cheap to manufactur'e may be readily applied to paper winding machines already in use as well as to those in the course of construction and while it is shown mounted on shield 4 it may be otherwise suitably mounted.

From the above description it will be seen that this guard may be either manufactured and sold as an article of manufacture, or, it may be embodied in the winders when constructed. r

lVithout further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention'or its scope as claimed.

We claim 1. The combination with a paper winding machine having a drum provided with a shielo; of a guard hingedly mounted on said drum shield and adapted to rest on the roll of paper being wound andprotect the space between said roll and said drum.

2. The combination with a paper winding machine having winding drum and means for supporting a paper roll being wound; of a guard to protect'the space between said roll and drum comprising a suitably mounted pivoted bar having a plurality oii laterally extending fingers to span and cover the space between the drum and roll, and means for yieldably holding said fingers engaged with the periphery of the paper roll.

'3. The combination with a paper winding machine having a winding drum and means for supporting the paper roll being wound; of a guard mounted to span the space be tween the roll and the drum, said guard being hingedly mounted, and means for supporting and holding the guard in inoperative position to provide for the removal-oi the roll when completed and the insertion of a new core.

.4. A guard for a paper winding machine comprising a bar having a plurality of spring hinges for connecting it with a suitable support, a plurality of longitudinally spaced laterally extending fingers carried by said bar and adapted to span the space between the drum of a machine and the roll of paper being wound thereon.

5. A guard for a paper winding machine comprising a bar having a plurality of spring hinges for connecting it with a suitable support, a plurality of longitudinally spaced laterally extending fingers carried by said bar and adapted to span the space between the drum of a machine and the roll of paper being wound thereon, an arm carried by said guard, and a rest to receive said arm when the guard is swung into inoperat've position.

6. The combination with a paper winding machine having a winding drum and means for supporting a paper roll being wound; of a guard mounted to span the space between said roll and drum and comprising a bar having means for hingedly supporting it adjacent said drum in position to span the space between the drum and the roll, an arm carried by said guard, and a standard located adjacent said drum and having a seat to receive said arm when the guard is swung into inoperative positioinand means on said standard for guiding said arm into said seat.

7. The combination with a paper winding machine having a winding drum and means for supporting a paper roll being wound; of a movable guard mounted to span the space between the roll and the drum, rest on and move with the roll being wound and thereby covers the said space at all times during the winding of the roll. I

8. The combination with a paper winding machine having a drum provided with a shield; of a guard mounted on said drum shield and adapted to rest on the periphery of the roll of paper being wound and to move therewith to conform to vthe size oi the roll being wound and thereby protect the space between said roll and said drum.
